Offset Conflict

In plugin settings try enabling “Prevent other scripts from handling plugin’s links” under “Advanced options”.
This should remove theme’s scrolling functionality from the links that are handled by “Page scroll to id”.

Let me know if this helps

The shortcode you’ve added is not correct. The offset is not an attribute of the target shortcode. It’s an attribute of the link shortcode. In other words, the offset goes on the links (not the targets).

If you simply want to “move” the gallery down (as with the rest of your sections), you can simply give it a top padding equal to the other sections top border. So maybe the solution you need is to add the following CSS:

#gallery{
    padding-top: 74px;
}

If you want to use an offset value for all your links, you should add the value you want in plugin settings “Offset” field.

No problem 🙂

You can add the extra top padding and subtract the same value from the top margin so everything stays visually the same. For example:

#gallery{
    padding-top: 74px;
    margin-top: -74px;
}

The link-specific offset can be applied on the link shortcode. To add one on a WordPress menu item, you’d need to do it via javascript (unless the theme allows HTML data attributes on menu items).

Glad I helped. Thanks a lot for your review 🙂
